i need to parse the actual content for the real title... lots of time the metadata gives wrong one.

Get Outlook for iOS

I think I understand but let me check. The title in the metadata isn't the text that would be recognized by a human as the title of the document if they were reading it on screen. If that's the case, take a look at our PDF Tools / Extract API.

Hi thanks for your reply.

 

basically i used the previewPDF function in window.AdobeDC.View class to render a pdf from a URL. 

 

and after it loads the PDF automatically, i want to get a raw arrayBuffer content of the loaded PDF so that i could do some processing on it. 

 

So i wonder if there is an API for requesting the raw pdf buffer.

 

I know that annotationManager.removeAnnotationsFromPDF returns the PDF buffer, but to use this function, i have to set the "IncludePDFAnnotations" to true, which I don't want, cos the additional save button will appear...

At this time, you can't just get the PDF arrayBuffer whenever you want it. As you noticed, only a few API calls will give that to you and there currently isn't any way to write the modified buffer back without reloading the PDF. My suggestion would be to get the PDF via fetch and then pass the content to AdobeDC.View as a Promise after you've done whatever processing you need to do on the PDF.
